SPINDLE-BEA-BING.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed May 11, 1907. Serial i510. 373,184.

To all whom-it may concern:

Be it known that I, THOMAS W. MORGAN, a citizen of the United States of America, and

a resident of Waterloo, Blaekhawk county, Iowa, have invented certain new and useful Improvements lIl Spindle-Bearings, of which the following is a specification.

My lnvention relates to improvements in spindle-bearings, and the object of my improvements 1s to furnish removable bearingseats for anti-friction means interposed between' the spindle end and such seats, such bearing seats also being provided with suitable means for adjustment. This object I have accomplished by the means which are hereinafter described and claimed, and which are Illustrated in the accompanying drawing, which is a central vertical axial section of my improved spindle-bearing, showing the antie friction means in situ and the whole ad usted' to Working position.

The external surface of the bushing is of the form of a truncated cone, intended for insertion into some'opening of similar registering .shape in a supporting frame. Another bushing f having afillet onits outer portion at the top is inserted into the upper part of the bushing g, the fillet resting on the upper edge of said bushing g. The bushing f serves as a hearing for the spindle-end a. The lower part of the inner peri hery of the bushing g is threaded so as to at. mit therein the'adjustable bearing-seat h which has a downward extension is also threaded and'a lock-nut ithereon. Resting upon the upper end of the bearing-seat h is a short cylindrical body e, whose inner-vertical bore is slightly greater in diameter than the diameter of the antifriction ball (Z to be contained therein. The

40 cylinder 6 is movable vertically with the adjustable bearing-seat h upon which it rests.

I have rovided removable bearing pins 1) and c, 'eac 1 having convex bearingfaces op is thereby posed to each other, for the reception of the ball (Z therebetween. The pin 6 is formed as a truncated cone to fit into a like formed seat in the-lower end of the spindle-end a. The pin 0 is of like form with b, and also seated in a like seat in the top of the adjustable bearmg-seat h.

The bearing is assembled by first screwing therein the bearing-seat h to the required height, with the bearing-pin a therein, then introducing the cylinder 0, then the ball (Z,

then the bushing f, and finally the spindleend a with its bearing-pin b. The bore of the easy to remove them and substitute others when their bearing-surfaces become too much abraded. Having described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

A spindle-bearing, composed of a bushingsleeve, an adjustable bearing-seat therein, a removable bearing-pin in said seat, a spindle rotatable in said bushing-sleeve, a removable bearing-pin in said spindle-end, a ball interposed in bearing contact between said bearing-pins, and a hollow bearing on said bearing-seat adapted to inclose said ball and prevent sidewise movement thereof.
